A chassis support member is mounted on the frame for movement in an X direction. A chassis having spaced apart parallel box rail members is movably mounted on the chassis support member for movement of the chassis in a Y direction. A rotary arm extends from the chassis, and a flexible lance guide hand fastened to a distal end of the rotary arm is configured to maintain a plurality of flexible lance guide tubes in parallel alignment with the row of tubes irrespective of an angle between the rotary arm and the frame. The system may include a lance drive and a snout connected between the lance drive and the positioning apparatus.
